美国派克PARKER液压阀[PARKER换向阀]Parker派克D3W/D3DW系列带电感位置控制电磁换向阀是一种通过电磁铁直接操纵的带电感位置控制的2位4通换向阀，可被用作监控阀。可以有选择的对初始位置或终点位置进行监控。只有单电磁铁阀可以用于位置控制。断电时换向阀的可靠位置为初始位置，其通过复位弹簧来保持的。美国派克PARKER液压阀液压阀（即控制元件）在液压系统中控制和调节液体的压力、流量和方向。根据控制功能的不同，液压阀可分为村力控制阀、流量控制阀和方向控制阀。压力控制阀又分为益流阀（安全阀）、减压阀、顺序阀、压力继电器等;流量控制阀包括节流阀、调整阀、分流集流阀等;方向控制阀包括单向阀、液控单向阀、梭阀、换向阀等。根据控制方式不同，液压阀可分为开关式控制阀、定值控制阀和比例控制阀。
液压阀可分为普通液压控制阀、伺服控制阀、比例控制阀。根据安装形式不同，液压阀还可分为管式、板式和插装式等若干种。
液压阀的基本结构主要包括阀芯、阀体和驱动阀芯在阀体内做相对运动的操纵装置。阀芯的主要形式有滑阀、锥阀和球阀；阀体上除有与阀芯配合的阀体孔或阀座孔外，还有外接油管的进、出油口和泄油口；驱动阀芯在阀体内做相对运动的装置可以是手调机构，也可以是弹簧或电磁铁，有些场合还采用液压力驱动。 美国派克PARKER液压阀在工作原理上，液压阀是利用阀芯在阀体内的相对运动来控制阀口的通断及开口的大小，以实现压力、流量和方向控制。液压阀工作时，所有阀的阀口大小、阀进、出油口间的压差以及通过阀的流量之间的关系都符合孔口流量公式（q＝KA·Δp m），只是各种阀控制的参数各不相同而已。
